(Fatwa: 1115/728/L=1434)

The husband may put his wife in the grave. Who told you that the husband cannot put his wife in the grave?
قال الإمام فخر الدين خان : يكره للناس أن يمنعوا حمل جنازة المرآة لزوجها مع أبيها وأخيها ويدخل الزوج فى القبر مع محرمها استحساناً (خلاصة الفتاوى: 1/225)
However, the husband is not allowed to touch the wife. The reason is that all the genealogical and causal relations come to an end after death and the wife becomes like strange.
قال عليه السلام: "كل سبب ونسب ينقطع بعد الموت إلا سلبى و نسبى" (در مختار مع الشامى: 3/90)
